TYPEWRITING MACHINE Application October 28, 1940, Serial No. 363,140 y 5claims. (01497-179) AThis invention relates to work-sheet-tabulatf Awork sheetmay be divided into a multiplicity of: tabulating columns,say, a series of fifty suc cessive columns each including three or moreletter spaces as exemplied by the columns k of the work sheet at Figure5.

A given line of typing done on the Work sheet may include entry in aselected one or more of said columns. But column selection may vary forevery line in that entries will not necessarily be in the same column orcolumns for diierent lines.

An object of the invention, therefore, is to provide tabulating-stopmechanism and controls therefor whereby for each line the appropriatecolumn or columns may be selected and the tabulating carriage may bemoved directly to a selected column without stopping at intermediatecolumns. v

A stop rack including a stop for each of said multiplicity of columns ispreferably mounted on the carriage which travels laterally fortabulating. Each stop is settable from a normally retracted position onthe rack to an effective position wherein it may be engaged by acounterstop on the main frame. The counterstop is projectible into thepath of the set rack-stop by operating a conventional tabulating keywhich f also serves to release the carriage for an ensuing spring-driventabulating jump which is gaged by means of the set rackstop andcounterstop.

A further object is to provide for facilitating the selective setting ofthe rack-stop or stops.

according to the requirements of a given line oi typing. This may beaccomplished by providing a key-operable stop-setter for each of themultiplicity of rack-stops. There are provided, therefore, according tothe present instance, fifty stop-Setters with their stop-setting keys ina conveniently accessible array on the carriage.

A further object is to provide for automatic restoration of a'setrack-stop after the latter has served its purpose during the typing of aline. Such restoration is necessary in order that a rackstop settingsuitable for one line will not stand for a succeeding line which mayrequire a diierent rack-stop setting. is made automatic so as not torequire attention of the typst whose work, therefore, in a tabulatingoperation is limited, as far as said fifty columns are concerned, tomerely selecting and operating a stop setter and operating the usual Therack-stop restoration counterstop projecting and carriage releasingtabulating key.

Another object is to eiect the automatic rackstop restoration by using asimple, inexpensive device in combination With the rack Stops.

Another object of the invention is to correlate structure embodying theaforesaid rack-Stops and stop-Setters with an existing design ofbookkeeping machine vsuch as exemplified in H. L. Pitman Patent No.2,160,487, dated May 30, 1939. In such machine, the carriage mounts aplurality of column units each of which controls computing mechanism.v

Another object is to provide for readily placing the stop setter atdifferent letter space positions of the carriage in accordance withvariations in the column spacing of the stops used with the rack. Inrespect of this, the rack may include a stop at each letter space sothat it will not be necessary to shift rack-stops along the rack butmerely to shift the stop-setter according to any desired change'ofcolumn-spacing intervals.

With these' and other objects, features, and advantages in view, theinvention consists of nove1 features of construction and combinations ofparts as set forth in the following description and the appended claims.

In the accompanying drawings:

Typing carriage C has a frame i5 which runs upon a front rail, notshown, and a rear rail I6 on main frame F of the machine. A revolubleplaten I8 is journaled in side members IS of the carriage. The carriagealso includes the usual upward and rearwardly sloping paper table 20 andbottom apron 2i.- Pressure rolls 22 cooperate with the platen to move awork sheet upon rotation of the vplaten as by line-space mechanism,

top wall at the side of the rack slot to detent the stop in itsineffective, retracted, position or in its effective, projected,position in the rack, each stop being vertically movable in the rackbetween said positions. A shoulder 26 of each stop may engage the rackside wall to limit depression of the stop to effective position.

A counterstop-forming reed 28, in a housing 29, is vertically movablebetween a depressed position and a raised position in which its upperend is in the path of the effectively set rack- Operation of atabulatingkey, not shown, raises the counterstop 28 to eiective position andcauses release of the carriage from the usual escapement device 36 forensuing leftward tabulating movement by the usual spring motor 3|. Thetabulator rack 23 and its stops 24 are substantially as shown in W. F.Helmond Patents No. 1,901,162, dated March 14, 1933, and No, 2,053,079,dated September l, 1936. There may be either a single reed 28, or adenominational set of such reeds and corresponding denominationaltabulating keys.

The carriage is also provided with one or more column units 33 and arack frame 32 for such units substantially as shown in the aforesaidPitman Patent No. 2,160,487. Each column unit 33 includes tappets forengaging-denominational jacks 34 and register selecting cam plates 35 ofcomputing mechanism, not otherwise shown. Said rack frame 32 for saidunits includes a front rack 36, a rear rack 31, and side brackets 38 towhich racks 36 and 31 are rigidly connected. Rack supporting arms orbrackets 39, 46 and 4I are fixed to carriage frame I as by screws 42 andhave upturned parts 43 to which the tubular rack 23 is secured at itsfront wall by screws 44. The left-hand bracket 39 presents, above rack23, a horizontal plate 45 having a notch 46 and, similarly, theright-hand bracket 4l presents a plate 41 having a notch 48. Saidnotches 46, 48 receive studs 49 of the rack frame 32 and the latter hasa latch lever 56 releasably engaging a stud 5I of bracket plate 41, rackframe 32 being thus detachably supported by the carriage with its frontrack 36 adjacent and behind the tubular rack 23. The rear end of eachcolumn unit 33 runs in a trackway 52 while the unit traverses acomputing zone.

Some of the tabulating stops 24 may be set permanently in effectiveposition for a given work sheet form. But others of thestops 24 aresettable selectively for each line of typing on the form.

For example, referring to Figure 5 which represents a work sheet recordof telegraph and cable trafc, each of the columns beginning with thedate column and up to and including the Words column is represented by apermanently set stop 24 in the rack. But in any given line, an entryfollowing the Words column may fall within any one of the numeroussucceeding columns lc each of which represents a different country andthe entry therein represents the number of words dispatched.

For each of such succeeding columns 1c, there is provided a stop-setterin the form of plunger 54 standing above the appropriate stop 24. Thework sheet columns corresponding to said plungers accommodate, say, upto three letter spaces each with the exception of certain wider columnswhich represent countries, such as U. S. A., having a comparativelylarge volume of trame. The stop-setting plungers 54 are spaced accordingto these narrow and wide column spacings of columns lc. Upper and lowerguide and spacing combs 56 for the stop setting plungers 54 are in theform of flanges of a vertical plate 55 and have slots 51 atletter-spaced intervals. The plungers 54 are spaced in such of the slots51 as will distribute the plungers according to the required columnspacing. Each plunger has at its top a nger key 58.

To avoid crowding the keys 58, the latter are staggered by arrangingthem in upper and lower rows, each row comprising the keys of alternateplungers. The lower ends of all the plungers 54 abut or rest upon thetop edges of their corresponding stops 24. The plungers having keys 58in the lower row are of course shorter, say, by one inch, than thosehaving the upper row keys. The plunger slots 51 of each comb open intothe edge of the comb but are closed by means of a strip 59 whichoverlies the comb and is secured at its ends to the comb by screws 60.Each plunger is in the form of a at reed and has a notch 6l to formupper and lower shoulders 62 opposed by the upper strip 59 to retain theplunger vertically. The upper shoulder 62 may strike the top of theupper strip to limit depression of the plunger in depressing theunderlying stop 24 to its eective position. The plunger supporting plate55 is mounted on the carriage by setting its lower comb 56 and a spacer65 upon and securing same to the righthand bracket plate 41 as by ascrew 60, and by securing said plate 55 by a screw 61 to an upstandingextension 68 of the intermediate bracket 48.

In starting a line of typing on the work sheet, the carriage starts froma fully returned position determined by a margin stop, not shown. Thecarriage is tabulated by means of the permanently set stops 24 to eachcolumn up to and including the Words column. Then, according to which 0fthe succeeding columns is to receive an entry for the instant line oftyping,a plunger 54 is depressed or will have been depressed to 4depressthe corresponding stop 24. A stop 24 having thus been set by its plunger54, the tab'- ulating key, not shown, is depressed causing the carriageto be tabulated to the column corresponding to the operated plunger 54.After typing in this column, and perhaps also in succeeding columns, asmay be determined by depressing other plungers 54, the carriage may bereturned to its starting position and the stop or stops 24 that wereselectively set by means of the stop-setting plungers 54 may be restoredpreparatory to typing another line.

The return movement of the carriage effects such restoration of theselectively set stops automatically by the following means: A support 12is i'lXed to the back of the machine frame F by screws 13 and has an arm14 presenting at the proper location a pivot stud 1 for a stoprestoringcam 16. Said cam 16 is yieldably disposed in the path of the set stops24 by being normally kept by a spring 11 in abutment with a stop pin 18on arm 14. At return movement of the carriage, any one of the stops 24that was set by means of its plunger 54 encounters and overrides cam 16which is at this time backed by and reacts on stop pin 18, therebycausing the set stop to become restored upwardly to its ineffectiveposition in the tubular rack. But at the movement of the carriage intabulating direction, the set stop 24 in traversing the cam 16 merelyturns the latter idly about the pivot stud 'I5 and away from stop pin I8`contrary to the force of the spring 11, the latter being effective torestore the cam after the Stop, `moving in tabulating direction, haspassed the cam. The arm 'I4 may present the cam 'I6 in such positionthat it is in the comparatively wide space between the stop 24 for theWords column and the rst selectable stop (for the U. S. A. column) whenthe carriage is in fully returned position as in Figure 4.

The rack frame 32 may have a column unit 33 for the Words column tocontrol a totalizer, not shown, for totaling all the amounts typed inthat column. Each of the wilder selective columns lc, such as the U. S.A. column, may also have a column unit 33 to control a totalizer, notshown, to total all the amounts typed in such column. The totals aretyped at the foot of the columns by copying them from the correspondingtotalizers; th-e totals of the narrower selective columns are usuallysmall and may be computed mentally and then typed at the foot of thesecolumns. A check is had by comparing the sum of totals of all theselective columns with the total of the Words column.

It may be explained that in the type of computing machine exemplified inthe aforesaid Pitman patent and herein contemplated, the column unit 33usually projects forwardly from the rack 36 to present a tabulating stopcooperative with the counterstop 23; in the present instance, however,such forward projection and its tabulating stop is omitted or cut ofifrom each unit 33 and instead a proper one of the stops 24 is used, suchstop 24 being either permanently set in effective position as for thewords column or being selectively settable by its plunger 54. A toolsuch as the tip of a screw driver may be inserted over and may ldepressthe stop 24 which is to be set .A

permanently, and, similarly, a permanently set stop may be restored. Cam16 is disposed relatively to the permanently set stops so as not to bein the path of the latter and restore same at return of the carriage.

Since the plunger combs 5S have a plungerreceiving slot 5l at eachletter space within the range of selectively settable stops, the columnspacing of the plungers is not fixed but may be varied as desired. Byloosening the screws 60, the upper guide strip 59 may be movedbackwardly to release the plungers 54 for placement in one slot oranother. Said strip 59 may have oblique, elongate holes 85 for thescrews 3D so that by moving the strip endwise by its nger pi-ece 8|, itis at the same time moved away from the plungers to release the latter,or toward the plungers to close the slots 5l for sli-dably confining theplungers. A plunger-designating scale 82 marked to represent theselective columns k of a particular work sheet is presented adjacent theplungers 54 by being retained in edge grooves provided by a clip 83 xedto the front of plate 55.

The portion of the work sheet trailing or delivered from the platen maybe kept clear of the scale 82 and the plunger keys 58 by being keptwithin a scroll-like container or guide 84, fixed to the paper table 23,to guide the trailing or delivered portion of the sheet upwardly andrearwardly from the platen and then reversely away from the scale andkeys, Figure 3.

lt will be seen now that, in respect to typing any line on a work sheetsuch as that in Figure 5, tabulating the carriage to any one of thenumerous selective columns lc requires, preparatory to operation of theusual tabulating key, not shown, only an operation of the appropriateplunger 54 to set a corresponding stop 24. Each required subsequentrestoration of the set stop is taken care of automatically by means ofthe returning carriage. It will also be seen that the structure isinexpensive, is applicable to existing designs of machine, and provides,in a simple way, for varying the column spacing of the plungers.

When any plunger 54 is depressed, it may continue to rest upon the topof the correspondingly depressed stop 24 and is restored upwardly by thedescribed restoration of said stop 24.

The Figure 5 work sheet having the numerous selective columns lc isaccommodated by using a wide carriage, for example, a carriage knownnominally as a 26-inch carriage. The rack structure is of correspondingwidth.

Variations may be resorted to within the scope of the invention andportions of the improvements may be used without others. f
